Application m June. 16,

This invention relates to shingles, and it has for one of its objects providing a method 'for forming shingles out of large sheets of shingle material, so as to produce individual or strip shingles which can be assembled to form lon'gstrips oi associated shingles having ornamental and useful projections and recesses on one edge, the-contour of the edge of the entire strip being symmetrical, .and'the method being such that the contour of the edge may be infinitely varied without departing from the general method employed. Furthermore, the assembled strips are so formed that they may be assembled with other strips so that the ornamental ex posed edges of the adjacent strips will. form 'pleasing and symmetrical designs on a roof,

. view of a plurahty of .the shingles assembled, and as they will appear when laid on a roof; Fig. 4 is. a plan view indicating the application of the method to the roduction of a modified form of shingle; ig. 5 is a plan view of a method of cutting a modified form of shingle; Fig. dis a plan view of a single strip shingle showing a further modification, and Fig. 7 is-a plan view indicating the method of forming the shingles illustrated by Fig. 6.

The shingles illustrated in the various figures are what are ordinarily called strip shingles, as each comprises more than one section, or what appears to be more than one individual shingle. In the application of my invention it .is immaterial whether the shingles are strip shingles or individual shingles or, if strip shingles, how many seetions there may to individual or strip shingles refers to the be. Hence herein reference shingles as illustrated in contra-distinction from the entire strips of shlngles when assembled. I

It will be seen by Fig. 3 that the individnecessary to .are bein width o the lapping portion 14, but with- 926. Serial n; naive.

- ual shingles 10 are assembled in strips which are laid horizontally on the roof and which overlap the underlying strips of shingles. Eachof these strips '11 is physically independent of the others, as the overlying strips may be made to lapeon as much as may desired. Varying the amount of lap, however, will vary the appearance of the design, and in this case the lapplng is made so asto form a symmetrical geometrical figure which is substantially octagonal. In forming the strips 11 it will be seen that the adjacent ends of the shingles lap on each other so as to prevent leakage between the adjacent ends, and also that the formation of the ends of the shingles is such that this lapping is accomplished without dlStOI'tlllg'lIl anyway the general design.

'Also the exposed edges of the ends of the.

shingle are symmetrical with reference to the figures themselves, as in each case the exposed edge is midway between two octagonal designs, and is at right angles to the axis of the strip of shingles. I

'1 0 produce these various results, it is deslrable to provide a method for forming the shingles properly and with the minimum amount of waste material. The method which I provide consists in severin the sheet of shingle material, from whic the shingles are to be formed, lon itudinall from one end to the other along llnes whic conform to the design desired. Inasmuch as the exposed edges of all of the shingles have similar contours, the desired result is produced by having the contours of the projections on the edges of the shingles homologous but. complementary with the contours of therecesses therein. That is, the edges of they projections 12 are similar to the recesses 13 in each case.

But, in the formation of'the provide material for lappin the ends, and ence a portion 14 is provide on the end of each shingle which is to underlie the adjacent end of another shingle in the same strip; and, to provide this lapping portion without distorting the symmetry of the edges, my method is to cut out a waste piece 15, which separates the edges 16 and 17 of two adjacent shingles which formed a distance equal to the out in any other way varying the mmet of the line along which the sheet is being the underlying strips I shingles it is severed. This waste piece is formed for each of the shingles and it is immaterial how many projections 12 or how many sections the shingle may contain, there Wlll be but one waste piece. In order to form the shingles from the longitudinal strips which are being severed from the sheet, transverse cuts 18 are made; and in order to have the lapping edge of the shingles symmetrical with the figures, as indicated, these transverse cuts are in the central portions of the projections adjacent the waste iece and extend out to the nearest edge of the severed strip.

Although I have indicated in Fig. 1' a narrow sheet from which two strips of shingles are being formed, yet it will be understood that the sheet may be. sufliciently wide to form four or more of these strips of'shingles.

A consideration of the drawings will show that theshape of the projections and recesses may be varied as much as may be desired without departing from the method of forming the shingles set forth. This is indicated by the rectangular shaped projections and recesses of Fig. 4, in which the corners 20 are right angles and the outer edges 21 of the projections are straight and S1mlli1 in length to the bottoms 22 of the recesses, which are also straight. In this case the waste piece 23 is in the form of a rectangular parallelogram.

Fig. 5 shows afurther modification in which the ends 25 of the ,projections are semi-circular and the .bottoms 2 6 of the recesses are similar in size and shape. 'In this case the waste piece 27 has opposite edges corresponding in contour to the edges of the. shingles from the center of a projection to the center of a recess, and it will. be seen that this is true with each of the other modified forms. In the claims herein I have referred to the line along which the horizontal cuts are made as bemg a wave line with crests and valleys which have similar contours. This is more graphically shown by the lines of Fig. 5 as these lines are all curved, but the intention is to, include by the expression broken lines as well as curved lines, such as are indicated in the other figures.

Fig. 6 shows a further modified form of shingle in which recesses 30 are formed, and locking tongues 31 corresponding in sha to the recesses are formed on the opposite end of the shingles. By means of these tongues the exposed edge of one'shingle may be looked under the adjacent end of an underlying shingle as indicated by dotted lines 32. Otherwise these shingles are substantially the same as those indicated by Fig. 2; and Fig. 7 shows the method of cutting these shingles from a sheet, which corresponds to the method of cutting the othershingles; and in shape the shingles, except continuing said severing in a similar man- 2. A method of for the recesses 30 and the tongues 31, are similar to those of Fig. 2. The recesses 30 definitely determine the amount of lap, so that the laying of the shingles is expedited thereby.

Guide means, such as the notches 34 may be formed so as to assist in laying the shingles. In forming the strips of shingles the edge of the overlapping shingle is registered with the notch, as indicated by the dotted line 35.

I claim as m invention:

1. A metho of forming shingles from a strip of shingle material, consisting in severing the strip longitudinally along a wave line having homologous crestsfand valleys, until a predetermined point of separation is reached,.and, from. this point consisting in severing the strip along two separated complementary lines meeting at another oint, then, from the point of meeting, consisting in severing the strip longitudinally along a line similar to the said wave line, until another point of separation is reached, and in ner so long as maybe desired, thus forming. independent severed strips, at the same time the method includes the severing of said severed strips along transverse lines extending from certain equally spaced crests and 05 valleys to the respective nearest edge of said shingle material strip orming shingles as set forth in claim 1 in which said complementary lines form symmetrical continuations of the respective wave lines preceding and following said points of separation and meetmg.

3. A method of forming shin les according. to claim 1 in. which the severing is along as many transverse lines as there are (points of separation and meeting and the sai lines are equal distances from the respective points.
